Every figure shows its source. Where a source is missing, the number is a placeholder — and it is never written as fact.

Ability details

  • Glory in Death

    After being killed, Sion will temporarily reanimate with rapidly decaying Health. His attacks become very rapid, heal him, and deal bonus damage based on his target's maximum Health.

    Passive — never cast

  • Decimating Smash

    Sion charges a powerful swing in an area in front of himself that will deal damage to enemies when released. If he charges for enough time, enemies hit by the swing will also be knocked up and stunned.

    Cost 45 ManaCooldown 10/9/8/7/6sRange 10000

  • Soul Furnace

    Sion shields himself and can reactivate after 3 seconds to deal Magic Damage to enemies nearby. When Sion kills enemies, he passively gains maximum Health.

    Cost 75/80/85/90/95 ManaCooldown 15/14/13/12/11sRange 500

  • Roar of the Slayer

    Sion fires a short range shockwave that damages and slows and reduces the Armor of the first enemy hit. If the shockwave hits a minion or monster, it will be knocked back, damaging, slowing, and reducing the Armor of all enemies that it passes through.

    Cost 35/40/45/50/55 ManaCooldown 12/11/10/9/8sRange 800

  • Unstoppable Onslaught

    Sion charges in a direction, ramping up speed over time. He can steer his charge slightly with the mouse cursor location. When he collides with an enemy he deals damage and knocks them up based on the distance he has charged.

    Cost 100 ManaCooldown 140/100/60sRange 7500

Counter plan — how to beat Sion

  • Build percentage damage — flat penetration falls off against the stats it stacks

  • Avoid extended fights — its sustain grows with every trade it survives

  • Punish the cooldown — Sion is exposed while its rotation is down

  • Ward the flank — vision is what turns its best opening into a worse one

  • Respect the spike — Riot rates the kit 5/10, so a practised player gets more out of it than the average

Methodology

Data window
512,340 games on patch 26.16, Ranked Solo/Duo, NA. Last refreshed 20 Aug 2026.
Rank aggregation
Emerald+ and above, pooled. Splitting further leaves samples too small to separate a real effect from noise.
Role assignment
A champion is filed under the lanes it actually plays, not the one class it belongs to — which is why several appear in two.
Counters
A matchup, not a tier gap: how this champion does into that one specifically, over that pairing’s own games.
Minimum sample
The confidence indicator beside every rate is driven by how much of the window this champion appears in. A low reading means read the figure loosely, not that it is wrong.
Why a build is not a cause
The best-scoring build is the one the best-placed players happened to take. Correlation is what a rate can show; it is not evidence that buying those items caused the wins.
Where the numbers come from
Names, classes, lanes, abilities, items and runes are Riot Data Dragon. Win, pick and ban rates are derived samples — Riot publishes none of them, and nothing on this page presents one as measured.
